CARPET STRETCHER AND TACKER.

SPECIFICATION forming part of Letters Patent No. 499,372, dated June 13,1893.

Application filed March 9, 1893.

' and I do hereby declare the following to bea full, clear, and exactdescription of the invention, such as will enable others skilled in theartto which it appertains to make and use the same, reference being hadto the accompanying drawings, and to letters of reference markedthereon, which form a part of this specification.

, The object of this invention is to facilitate and render more easy theoperation of laying carpet, and it consists in the improved carpetstretching and tacking device and in the arrangements and combinationsof parts of the same, substantially as will be hereinafter set forth andfinally embodied in the clauses of the claim.

Referring to the accompanying drawings in which like letters indicatecorresponding parts in each of the several views, Figure 1 is a frontelevation of the improved device. Fig. 2 is a side view of the same;Fig. 3 a longitudinal section taken on line m, Fig. 1; Fig. 4 a rearView showing acertain slide partly raised; Fig. 5 a section, on anenlarged scale, taken at line y, Fig. 1. Fig.6 is a section taken atline 2, Fig. 5, and Fig. 7 is a section taken on line to, Fig. 1.

In said drawings, a indicates a handled rod at the lower end of whichisatransverse block or piece, I), having a toothed plate, 0, at the backedge adapted to engage the carpet and, when the handled rod is pushedupon, to force said carpet into position.

The block, b, is chambered, as at d, and is provided with a valve orvalves 0, controlled by springs f, said springs tending to close saidvalves automatically. Above the block are passages g, h, which unite ati, and coincide with a hopper recess or receptacle j, in the valves.Connecting with the passage, h, is a tube is which extendslongitudinally along the rod a, and connects with a passage or chamber,Z, into which a series of tack chambers, m, open,the said chambers beingclosed at their outer ends by a slide, n, and at their inner ends wherethey connect with the cham- $erial No. 465,220. (No model.)

ber Z, by a valve ohaving a single opening or passage, p, thereinadapted to coincide with the tack chambers.

In line with the passage, 9, is arranged, longitudinally with respect tothe handled rod, ahammer rod, q, which slides in bearings r, r, and ispreferably held in its raised position, by asuitable catch 0", so thatit will not be loose and in the way when stretching the carpet.

In operating the device, the stretcher recep tacles or chambers m, m,are each provided with a tack; the toothed plate, 0, is then broughtinto engagement with the carpet and the latter forced into the desiredposition at which it is to be tacked. When in this position the valvedslide, 0, is moved longitudi nally into coincidence with one of the tackchambers and the tack therein drops, point foremost into the chamber, Z,through tube It I and passages h, 7;, into the hopper shaped recess orchamber, j, in line with the sliding hammer. rod, g, which is thenloosened from its catch, r, and forced downward. It engages the head ofthe tack and the latter is driven into the carpet, the valves 6, 6,being forced apart to admit the passage of the tack between. The hammeris then drawn up, the valves close together automatically, and thedevice is ready to be employed in connection with a repetition of the.operation described. The slide valve, 0, is regulated in its slidingmovements by a spring or snap, s, which engages a notched edge if, ofsaid slide valve, 0, as will be understood upon inspection of Figs. 1and 2, so that when the valve is drawn or pushed it will stop when theopening, 10, engages one of the chambers m.

I am aware that modifications may be made in the construction of thedevice without departing from the invention.

Having thus described the invention, What Iclaim as new is- 1.Theimproved carpet stretching and tacking device, combining therein thehammer, stretching rod and teeth and a series of tack chambers and aslide valve and passages admitting the passage of the tacks into linewith said hammer, substantially as set forth.

2. In combination with the carpet stretcher, a tack hammer and a seriesof chambers for tacks arranged in said carpet stretcher, means 10 valve0, passages h, t, 70, Z, for the tack, valves e, e, springs f, f,therefor and a hammer for driving the tack between said valves 6 6 intothe carpet substantially as set forth.

In testimony that I claim the foregoing I have hereunto set my hand this11th day of 15 February, 1893. 7
